Let me be clear: I am well aware of the problematic aspects of Facebook' s impact; I am particularly worried about the ease with which we sort ourselves into tribes, in part because of the filter bubble effect noted above (that's one of the reasons Why Twitter Must Be Saved). But the solution is not the reimposition of gatekeepers done in by the Internet; whatever fixes this problem must spring from the power of the Internet, and the fact that each of us, if we choose, has access to more information and sources of truth than ever before, and more ways to reach out and understand and persuade those with whom we disagree. Yes, that is more work than demanding Zuckerberg change what people see, but giving up liberty for laziness never works out well in the end.
